VALLEY AND RIDGE SHEETS FOR ROOFS.

SPECIFICATION formingpart of Letters Patent No. 235,351, dated December 14:, 1880.

Application filed June 17, 1880.

To all 'whom tt may concem:

Be it known that I, VALENTINE FIscHER, of the city, county, and State ot' New York, have invented a new and useful Improvement in the Valley and Ridge Sheets of Sheet-Metal Roofs, as fully set forth and described in the acconpanying specification and drawings, in which like letters represent like parts.

Figure 1 is a plan view of the lower die, shown as cast in two pieces and set on the anvil of the drop. Fig. 2 shows a Valley or ridge sheet after having been corrugated on its edges by the (lies.

The valley and ridge sheets of metal roofs as heretofore used have been fiat pieces. of sheet metal bent to fit the ridge or Valley of the root', and prior to my invention .the joint between these pieces and the corrugated roofing-sheets has been made by slitting the corrugations of the roofing-sheet at the end, lappin g the ends thus formed, and then hammering them down into asperfect a flat 'surface as could thus be obtained, which was nailed, soldered, or bolted onto the flat edges of the Valley or ridge pieces. This joint was not a good one, and the slitting of the ends of the corrugations in the roofing-sheets took much time and labor.

My improvement consists in corrugating the edges or sides of the valley` and ridge pieces with the same siz'e corrugations as are in the sheet-metal roofing, which corrugations in the Valley and ridge sheets shall be made in them in such position as to properly receive the corrugations of the roofing-sheets which are to fit into them.

I corrugate the edges or sides of these flat sheets to be used as the Valley and rid ge sheets as follows: I prepare a lower and upper die of cast-iron or other suitable metal, the lower one being shown in two parts in Fig. 1. These dies have on their working-faces elevations h h ot' the same size and shape, save length, as the corrugations in the roofing-sheets. These elevations are on the outer edges of the dies, or if the dies be made in two parts then on the outer edges respectively of these two parts, and they are cast on the dies at such an angle relative to the axial line of the dies, which line I indicate by x x, Fig. 1, as the corruga- (No model.)

tions to be made in the flat sheets are to bear to the axial line of the sheets. These elevations Iz h extend from the outer edges of the dies in toward the middle thereof far enough to make a corrugation on the edges of the sheet, as lereinafter explained, sufficiently long to admit of a good joint being made between the corrugated roofing-sheet and these ridge and Valley sheets-usually from three to four inches. The inner ends of these elevations on the dies round off and disappear into a flat surface, t i, between them by spreading sidewise and flatwise downwardly. The flat surface lying between the inner ends ot' these elevations is on a level with their bottoms. These dies (if made in a single piece) should be as wide as the flat ridge or Valley sheet is before it is corrugated; but in order that they may be easily made of the proper width to accommodate and correctly stamp any width of ridge or Valley sheet, I prefer to make them, both upper and lower, in two pieces-halves,

or nearly so--and I fasten these two halves firmly in position on the anvil and hammer of the drop (in which these dies are to be used for stampin g the corrugations in the sheet meta-l) by pourin g molten metal, preferably lead or Zinc, around them after they havebeen placed the proper distance apart, taking care that the molten metal does not come above the flat surface of the dies. (Seen at M, Fig. 1.) These dies are set on the anvil of the drop, and also fastened to the under side of the hammer of the drop, in such a position that the elevations on them run from the front of the drop backward to the rear of it and with the corrugatons on the outer edges of the dies.

The upper die, or its two halves if made in more than one piece, are counterparts of the lower die or die-pieces, and are placed in the under face of the hammer, so as exactly to fit or match into the elevations on the lower die when in use.

The operation is as follows: The dies being properly set and fastened, respectively, on the 5 anvil and the under side of the hammer, the worknan, when the upper die is elevated, introduces the end of a Valley or ridge piece, as the case may be, which, at this time, is a flat sheet or strip, onto the lower die in such a oo position that it shall cover three, four, or more sheet or movement cornerwise as it is fed through the dies. e

I do not confine myself to Valley and ridge sheets corrugated simply with the usual wavelike corrugation, as any form of corrugation, nolding, heading, or other ornanentaton that is stanped or formed in the roofing metal can he reprodeed in the edges of the Valley or rid ge pieces by forming the dies to eorrespond of the elevations on the lower die. The drop is then tripped, and the hammer, falling, strikes up as many corrngations in the metal on its edges as there are elevations on the die heneath it. The upper die is then again elevated l and the sheet or strip is farther shoved in hei tween the dies, care being taken that the eorrugations just formed in it shall rest and cori rectly fit into the eievations and depressions thereto. of the lower die, so that they shall not be If the ridge or Valley pieoes are to be used orushed ont when the upper die fellson them. i on ridges or valleys whch lie at au angle, The npper die is then again allowed to drop, i either Vertiez lly or horizontally, to the line of and t strkes np still other corrugatons n i the eorrugatons n the roofing-sheets, then the metal, as before, and tlns the operation the corrugations must be stamped in the is repeated until the entire sheet or strip has sheets at nn angle, (more or less, as the ease heen fed through the dies, when it will have may le,) to the axial line of the sheets. aflatsurfaceinthemiddlepurttlereofthrough Having thus described my invention, what out its length, and eorrugztions on its two y lelain, and desire to secure by Letters Patedges corresponding to the elevztions on the i ont, isdie as sefelin Fig. 2, uld wllenf illt in gace t 1. %lute stanping-ee herilset fl'th,hfl\'. on eroo ie eorruga e en: so eroo n lllgt e sur ece n er m e par an( e esheets will nieely fit into these corrugatio s i mtions on their outer edges, as and for the on the Valley and ridge pieees and make a sug i purposes set forth. and handsoinely finished joint, which may 2.
